RAISING DEVICE FOR EORTABLE CNVEYERS. l

Application filed January 15,119.27. Ylerial No. 151,434.y

This invention relates to portable conveyers of the type used for 4loading coal, building materials and the like into receptaclcs or enclosuresJ and my main object is to provide a gearing to effect the raising ofsuch conveyers by power instead of by hand, as is the present practice.

A further object of the invention is to install the novel gearing in direct communication which the power elementalready on the machine, so that no radical changes in the design of the machine are necessary.

A still further object of the invention is to join the novel gearing with the gearing of the manual raising element, whereby to still make use of the latter gearing, saving the need of new part-s in that connection.

Another ob" ect of the invention is to so de.

sign the same that the manual raisingelement is immediatelyavailable for use in case the supply of power is interrupted.

A. final but nevertheless important object of the invention is to construct the novel gearing of few and simple parts, in order that its production and installation may not materially affect Vthe price of the machine.

lVith the above objects in view and any others that may suggest themselves from the specification claims to follow, a better understanding of the invention may be gained by reference to the accompanying drawings, in which Figure 1 is an incomplete perspective view of a typical portable conveyer showing a portion of the novel gearing prominently;

F ig. 2 is an 'enlargedk section on the line 2--2 of Fig. 1; and

Fig. 3 is a section on the line 3-3 of Fig. 2.

Portable conveyers of the prevalent type have, according to the specific showing in the drawings, a long trough 5 supported in inclined position in a Wheeled carriage 6. Chains 7 carrying flights 8 serve to move the material in which .the lower end of the trough is placed toward the upper end, the latter not being fully illust-rated. The lower end of the trough always rests on the ground or in the material, and the trough is sus* pended amidships in the carriage 6 in order to be vraised or lowered for t-he adjustment of the angle thereof to the proper dumping height. The trough swings within the carriage standards 9 and has a cross beam 10 to which is connected t-he lifting tackle 11 lead- `ing from winch drums 12 at the sides of the machine, The winch drums 12 are carried by a cross-shaft 13 journaled in bearing plates ll'carried by longitudinal frame members 15 of the machine. The plates 14C also have b-earings for a vertical shaft 16 cut with a worm ltrl to mesh with a gear 13a on the sha-ft'l. The shaft 16 receives a crank handle 17 at its upper end.

The construction thus far described is practically standard andinainly featuresl the apparatus for the raising and lowering of the trough by the turning of the crank handle 1-7 in one or the other directionl The connec tions for operating this apparatus by power will now be described. y

Forward of the winch drums 12, the trough .has a housing 18 for an elect-ric or O'asoline motor and suitable controls and connection-s with the conveyer chains 7 for the driving of the same. Of these parts but an intermediate gear 19 and its countershaft 2O need be shown for the present purpose. The countershaft 2O is connected by a clutch 21 to an extension shaft 22 leading into a gear box 23. In the latter, the extension shaft 22 carries abevel gear 24 which meshes withv a companion bevel gear 25 carried by a shaft 26 vertically eX- tended through the top of the box 23.` The outer end of this shaft carries av sprocket wheel 27 from which a chain 28 is passed to a comp-anion sprocket :wheel 29 mounted on the v shaft 16 below the crank handle 17.

It will now be seen that when the motor is in operation, the clutch 21 maybe engaged to put in motion the chain 28 for the operation Y of the shaft 16 and the balance of the troughraising mechanism. Suitable controlling devices for the speed and direct-ion of the power already4 being part of the equipment for the regulation of the conveyer chain operation,

and not being directly incident to the operation of the novel gearing, need no illustration.

A raising device is thus had which is both simple and eliicient, furnishes a short connection between lthe power element and the immediate raising gearing, yet enables the latter to be manually operated in the event that power is not available.

I claim Y 1. 1n a portable chain-conveyer, the com` bination with a power shaft in the drive for the chains and a crank shaft in the manual drive for raising the conveyer; of a clutch in the power shaft, a spindle parallel to the crank shaft, a gearingfrom the' driven part of the clutch to the spindle, alined sprocket wheels on the spindle and crank shaft ref spective'l-y, and a chain connecting the sprocket Wljlyeels. Y

I 2. In e portable chain conveye1111eans for manually elevating the eonveyer and ineludng a Shaft, e sprocke on said shait, power driven means 'for operating the chains of said conveyer and including a shaft, a stub-shajft mennted adjacent thereto, a sprocket on sind shaft and said stub Shaft for operating said devait-lang mechanism from the power drlve. In testnnony whereof-I afIX my slgnature.
